cisco-voip Serial interface state change cisco-voip Serial interface state change Rhodium Mon Apr 15 14:53:37 EDT 2013. Previous message:. Next message:. Messages sorted by: When you shutdown the signalling channel, effectively all the bearer channels are also shutdown as nothing can traverse them due to there being no signalling channel.
Even if the provider reset the circuit, that would not bring up a shutdown interface. That could be tested on a H.323 or SIP gateway. I am guessing that this is a MGCP gateway with ccm-manager config applied it where the router downloads the configuration file for itself off the CUCM. This would bring up the interface (D-channel) thus causing a restoration in service.
Troubleshooting Cisco interface biggybiggy Aug 6, 2012 12:29 PM I have a 2800 series Cisco router and my users are complaining that the router just keeps going up/down, usually at night.

Leaving the other 23 channels up. The PRI was still up. You just downed the channel that has the D-Channel on it. The reason it came backup is your Service providor received an alarm on they're side showing your PRI was down.
I'm assuming after a unspecified amount of time, they bounced the entire PRI to bring the channels back up. (That would the the AIS detected message, it's a test message) Downing the controller is the correct way to do this/ Mike On Wed, Apr 10, 2013 at 4:14 PM, Fred Hunt wrote: I’m trying to figure out why a serial interface seemingly changed its state on its own. We have a PRI that we are planning to decommission. I previously removed it from being routed to in CUCM and I shut down the serial0/0/0:23 interface, as shown in the log below: 021241: Mar 16 20:32:48.963 CDT:%ISDN-6-LAYER2DOWN: Layer 2 for Interface Se0/0/0:23, TEI 0 changed to down 021242: Mar 16 20:32:50.960 CDT:%LINK-5-CHANGED: Interface Serial0/0/0:23, changed state to administratively down Then, somehow the serial interface changed its state back to up. This occurred after what appeared to be a brief outage of the T1 service.
I was setting up a router today at a remote location and found I couldn't configure the options on the 'controller T1 0/0/0'. The ISP has finished their stuff and verified everything is up and running, the serial interface appears to be correctly configured but I can't configure the controller settings. Sh run doesn't show any controller at all. Sh controller t1 displays nothing.
Conf t controller t1 0 errors with the controller not being valid command. I suppose the controller has always been created by the time I've come along and I'm failing to do something but I can't seem to find out what via google or cisco. How do I create the controller t1 'interface' in order to get this thing up and running.
Digerati is using the right commands for a channelized T1. Maybe the controller he has isn't channelized? The new VWIC2 is both E1/T1 so maybe there are some different commands? I really don't know.
I've veried that the commands he points out work on my router.
